CULTlVATOR OR PLOW STANDARD.

SPECIFICATION forming part of Letters Patent No. 543,886, dated August6, 1895.

Application filed August 4, 1894. Renewed June 18, 1895. $erial No.553,237. (No model) To all whom it may concern.-

Be it known that I, Jackson H. MOLAIN, a citizen of the United States,residing at Pursley, in the county of Navarro and State of Texas, haveinvented certain new and useful Improvements in Cultivator or PlowStandards; and I do declare the following to be a full, clear, and exactdescription of theinvention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to the letters ofreference markedthereon, which form a part of this specification.

The special object of the invention is to improve the standard whichconnects the shoe or landside of a sweep-shovel or-bull-tongue plow withthe beam, so as to render it fixed and secure at any point ofadjustment.

Figure l of the drawings is a perspective view showing my inventionapplied; Fig. 2, a detailed view of the standard, and Fig. 3 a detailview of the shoe.

In the drawings, A represents the handles; B, the beam; 0, the standard;D, the rear brace; E, the sweep-shovel connected by the bolt and nute cwith the standard, and F the shoe which slides along upon the ground.This shoe is provided with the slots f f, through which pass the bolts fwhich, by means of the nuts f hold the standard adjustably to the shoe.

The standard 0 has at its lower end a horizontal rear arm 0, to allowthe two bolts f to be in the same horizontal plane, or thereabout, sothat the shoe cannot be displaced vertically and thereby affect thepitchof the plow.

The standard 0 is formed of parallel vertical metallic straps connectedby the rivets c 0, between which rests the plow-beam B, the pivot-bolt 0which passes loosely through the front eye of the rear brace D, and thebolts f which permit the horizontal adjustment of the shoe. Byunclamping the pivotbolt 0 the standard may be moved forward or back onthe beam, so as to regulate the pitch of the shoe and plow. Thesweep-shovel has its front, end under anotch f of the shoe, while itsrear upper edge rests in a notch c of the standard, so that the shovelcannot possibly work up with the bolt e, whereby the shovel would soonbecome laterally displaced. The shoe has but a limited horizontal adjustment in connection with the standard.

What I claim as new, and desire to protect by Letters Patent, 'is- Inshovel plows or cultivators, the combination with the shoe F havingslots ff, the
